摘要
纳米纤维素（NFC）因其卓越的力学性能和可持续性特征，作为一种增强材料广泛应用于生物基复合材料中。本文探讨了纳米纤维素在生物基复合材料中的强化作用，重点分析其对复合材料力学性能的影响，并评估其在可持续发展中的应用潜力。通过实验和理论分析，发现纳米纤维素的加入显著提高了材料的拉伸强度、硬度和韧性，同时减少了环境负荷。纳米纤维素不仅提升了复合材料的性能，还支持了环境友好的设计理念，为生物基材料的广泛应用提供了有力支撑。

Abstract
Nanofibrillated cellulose (NFC) has been widely used as a reinforcing material in bio-based composites due to its outstanding mechanical properties and sustainability characteristics. This paper explores the reinforcing effect of nanocellulose in bio-based composites, focusing on analyzing its impact on the mechanical properties of the composites and evaluating its potential for sustainable development applications. Through experimental and theoretical analysis, it was found that the addition of nanocellulose significantly enhances the tensile strength, hardness, and toughness of the materials, while simultaneously reducing environmental burden. Nanocellulose not only improves composite performance but also supports environmentally friendly design concepts, providing strong support for the widespread application of bio-based materials.
Key words： Nanocellulose; Bio-based composites; Mechanical properties; Sustainability; Environmental friendliness
